Aerographene, also known as graphene aerogel, is a fascinating material that was discovered by scientists at Zhejiang University in China. It is the world's least dense solid, with a density of only 160 g/m3 (0.0100 lb/cu ft; 0.16 mg/cm3; 4.3 oz/cu yd), which is less dense than helium. This material has attracted a lot of attention due to its unique properties and potential … [Read more...] about Discovering Aerographene: The World’s Least Dense Solid
